State guidance · local review matters

What the rules allow here.

California’s ADU and JADU framework sets statewide standards, while parcel conditions and local review still affect a project. See the California HCD ADU guidance.

Some parcels may qualify for an SB 9 duplex or urban lot split, subject to statutory requirements and site-specific exclusions. Read HCD’s SB 9 fact sheet.

Home additions are reviewed under applicable local approvals and California residential building standards; requirements depend on the property and proposed work. See HCD building standards.

Los Angeles is phasing SB 79 in by transit stop; eligibility depends on your parcel.
